Effects of geosynthetics on reduction of reflection cracking in asphalt overlays
AbstractAn experimental program was conducted to determine the effects of geosynthetic reinforcement on mitigating reflection cracking in asphalt overlays. The objectives of this study were to assess the effects of geosynthetic inclusion and its position on the accumulation of permanent deformation. Geogrid position, type of existing pavement, temperature, and joint/crack opening were varied in 24 model specimens tested. Crack propagation under repeated loading was monitored. Results indicate a significant reduction in the rate of crack propagation in reinforced samples compared to unreinforced samples and type of old pavement (concrete or asphalt pavement), geogrid position and temperature affected the type of crack propagation in asphalt overlays. Placing the geogrid at a one-third depth of overlay thickness from the bottom provided the maximum service life.
